  • Page 4 The Model 3140A is also available in two other forms. The Model 3240A contains a Digital Indicator to display the analog output. The Model 3340A is identical to the 3240A, except that it also includes high-low limit monitoring. See separate Model 3200/3300 and Model 3300 Instruction Manuals.
  • Page 5 IMPORTANT: The unit is shipped with two spacer washers on the securing screws of the rear-panel I/O Connector. When panel-mounting the unit, you MUST REMOVE THESE WASHERS, so that the printed-circuit board may move for- ward about 1/8" during Step f, below. a.
  • Page 6 b. Remove the front bezel (four fillister-head screws fasten it to the metal housing--see Fig. 2). c. Make the panel cutout and drill the screw clearance holes shown in Figs. 1C and 2. The front bezel can be used as a template to define the rectangular cutout and to locate the clearance holes.
  • Page 7 AC POWER CONNECTION: Connect the supplied power cable to a 105-135 V-AC, 50-400 Hz source (for "F" versions, 210-260 V-AC; for "B" versions, there is no external power connection). This is a three-conductor cord, plug- ing into the AC power connector at the rear of the unit; the offset pin connects to earth ground.
  • Page 8 RANGE SELECTION: To access the internal bank of ten numbered range- selection switches, remove the 3140A's front panel (two screws near each edge--see Fig. 2). To select the desired full-scale frequency range, place in the ON (i.e., downward) position the switches indicated in Table 2, below.

SCALE SELECTION: Determine the full-scale output of the transducer in terms of the desired unit of measurement.
  • Page 10 3A. SPAN ADJUSTMENT: Apply an input signal with a frequency equal to the rated full-scale output of the transducer. Then adjust the Coarse and Fine SPAN controls to produce a readout on the indicator of the value de- termined in Step 2A, above--that is, of the full-scale transducer output in terms of the desired unit of measurement (e.g., 728.2 cfm).
